1.	Energy of an electron is given by E=−2.178×10−18 J×Z2n2:Wavelength of light required to excite an electron in an hydrogen atom from level n=1 to n=2 will be (h=6.62×10−34 J s and c=3.0×108 m s−1 )
Answer» Energy of an electron is given by $E = - 2.178 \times 10^{- 18} J \times \frac{Z^{2}}{n^{2}}$ : Wavelength of light required to excite an electron in an hydrogen atom from level $n = 1$ to $n = 2$ will be ( $h = 6.62 \times 10^{- 34} J s$ and $c = 3.0 \times 10^{8} m s^{- 1}$ )
